The aim of this article is to suggest a common preventive maintenance program for large turbogenerators used on onshore or offshore, the objective be generic, under intention allow owners different turbo generators brands level standardization. It motivation derives from lack literature approach, either publication own manufacturers old were found, in time where industry 4.0 productivity and av...

In the printing industry, where production never stops, it is very important to continuously maintain machine performance. If a breaks down, will stop and disturb process. Therefore, maintenance system must be managed efficiently solve those problems. The paper presents study results on continuous quality improvement of offset using preventive features. Offset process that involves multitude va...

Compared with time based maintenance (TBM), Condition based maintenance (CBM) can improved the availability of the devices and reduced the examining maintenance cost. However, CBM possibly arouse an unexpected interference on production process due to an unplanned maintenance activity in advance so that the stable-state operation of the system was influenced. As the system scale was larger, thi...

discharge from VA hospitals in 1976, comprising about 8 per cent of all discharge diagnoses. A study by the VA Nursing Service in 1977 revealed that there were 34 diabetes nurse practitioner clinics in Veterans Administration hospitals where the major focus was on patient/family teaching. This was second only to 44 hypertension nurse practitioner clinics. Most newly diagnosed and poorly control...

The paper generalizes a preventive maintenance optimization problem to multi-state systems, which have a range of performance levels. Multi-state system reliability is defined as the ability to satisfy given demand. The reliability of system elements is characterized by their hazard functions. The possible preventive maintenance actions are characterized by their ability to affect the effective...

This paper considers four options of warranty and preventive maintenance policy. The product is repairable and sold with a non-renewing free warranty policy. For products sold with warranty, preventive maintenance (PM) actions by manufacturers and/or buyers have an impact on the total costs for both parties. In this study, we deal with a model to study the effect of PM that carried out by the m...

PLTU memiliki peran strategis dalam sistem kelistrikan Indonesia, karena dinilai lebih ekonomis dan hasil energi memadai. Salah satu komponen adalah boiler. Boiler alat untuk mengubah panas menjadi gerak, menggerakkan turbin agar menghasilkan listr...

This paper presents a condition-based maintenance policy taking into account both maintenance cost and production capacity aspects for single unit deterioratin production system whose condition is periodically monitored. Imperfect preventive maintenance activities, which restore the production system to better states and might not be as good as new, are considered. We assume however that the sy...

In this paper, we consider a production system that must achieve a set of different requests during a finite horizon period. Among the various requests proposed, the objective is to select those to be satisfied so as to maximize the net profit. A sporadic maintenance policy is studied to minimize the maintenance costs by the achievement of perfect preventive maintenance actions after the comple...
